[Zope] filename property of variable

Mon, 9 Jul 2001 14:40:09 -0500

OK - here is my input form
<dtml-in "PARENTS[0].objectValues(['Specimen'])" sort="specimenid">
	<dtml-var sequence-item>
	<input type="file" name="<dtml-var id>" value="Add image to this
specimen"><br>
</dtml-in>

And here is my handling form:
<dtml-in "REQUEST.form.keys()">
    <dtml-var sequence-item>:<dtml-var expr="_[_['sequence-item']]"><br>
    <dtml-if "_[_['sequence-item']]">
        <dtml-with "_.getitem(_['sequence-item'])">
            <dtml-call
expr="manage_addProduct['ExtFile'].manage_addExtImage(id='test',file=REQUEST
.form[_['sequence-item']], create_prev=1, permission_check=1)">
        </dtml-with>
    </dtml-if>
</dtml-in>

When I run this I get the html source as

Specimen_288:<Specimen instance at 893b520><br>
Specimen_289:<Specimen instance at 8874568><br>
Specimen_291:<Specimen instance at 8936fb8><br>
Specimen_290:<Specimen instance at 86d6868><br>
Specimen_293:<Specimen instance at 89d9fe0><br>
Specimen_292:<Specimen instance at 88c22c8><br>
Specimen_286:<Specimen instance at 893b5e0><br>
Specimen_287:<Specimen instance at 87fc188><br>

Hope this helps!

I'm a little lost.  When I tried it, I got a non-empty string for each file
input field that had a filename, and there was an empty string for each one
where the user hadn't entered anything.  Isn't that what you want?  That
way, you can test to see if anything was entered.

Let me show you what I was testing.  Here is my form, with two file-type
inputs:

<html>
    <form action='see_request2 '>
        <input type='file' name='file1'><br>
        <input type='file' name='file2'><br>
        <input type='submit' value='Try It'>
    </form>
</html>

Here's my handling form, see_request2:

<html>
    <dtml-in "REQUEST.form.keys()">
        <dtml-var sequence-item>:<dtml-var "_[_['sequence-item']]">
        <dtml-if "_[_['sequence-item']]"> (passed if)</dtml-if><br>
    </dtml-in>
</html>

Here's the result, copied for the screen, where I entered "aaa" for the
first file name and nothing for the  2nd file name:

file1:aaa (passed if)
file2:

You see, it DOES differentiate between the fields where the user entered a
filename and those where the user didn't.

Isn't that what you want? If not, I need more clarification.  I'm probably
assuming something without realizing.  Better show us a (shortened) sample
of the form, at least.
